Type A behavior and its relation to personality variables in Swedish male and female university students

A questionnaire based on the Jenkins Activity Survey (JAS), given to 181 male and 280 female Swedish university students, showed that females had significantly higher Type A scores than males. Three factors were extracted by factor analysis, two of which, "speed and impatience" and "hard-driving", corresponded to two of the factors obtained by JAS in an American population of employed men (Zyzanski & Jenkins, 1970). The third factor was tentatively termed "engagement-involvement". Twelve male and 12 female subjects from opposite ends of the distribution were compared in terms of 22 personality variables measured by questionnaires. It was found that Type A subjects of both sexes scored higher on scales measuring anxiety-proneness, aggression-hostility, extraversion and neuroticism.     

Involvement in four future events as a function of temporal distance

Abstract.— A total of 91 Swedish high-school students, in four groups, estimated their degree of involvement in each of 4 potential future events, which were assumed to occur at 5 alternative points in time within the next 75 years. In addition, estimates were made of the relative importance of the events as well as of their subjective probability and influenceability. Factor analysis revealed two different time-involvement relations: (1) involvement decreasing slowly with increasing temporal distance for the two next decades. and then rapidly approaching zero, and (2) involvement decreasing rapidly for the nearest decades, and then slowly approaching an asymptotic value. Subjects representing the first trend gave consistently higher estimates of event probability. Relative involvement for the events was judged differently by subjects in natural-science and social-science lines of education.     

Performance under simulated offshore climate conditions

An experimental study was set up simulating the environmental conditions and work load among drillers and maintenance personnel offshore. Thirty-six male subjects participated in the experimental study involving 3h exposures with dry gloves, wet gloves or without gloves. The subjects were working on tasks involving heavy and light muscle work, dexterity and cognitive tasks. Body and skin temperatures and heart rate variability were continuously monitored. Neuropsychological and endocrinological parameters were intermittently monitored. The data from the work performance tasks showed that motor functions, both gross and fine, were impaired when working with wet and, especially, without gloves. Working without gloves also affected mental work tasks. The neuropsychological and physiological data confirmed the work task studies: working with wet or without gloves led to increased tremor and impaired finger dexterity. Furthermore, reasoning was consistently impaired throughout the exposures compared with working with dry gloves. The heart-rate variability data and the endocrine results also showed a significant central nervous stress reaction for the two hypothermic conditions compared with the dry glove condition. Especially for drilling further north these data should imply that both health and performance may be detrimentally affected during working under such conditions with insufficient thermal protection.     

Evaluation of long term effects of phonemic awareness training in kinderarten: Illustrations of some methodological problems in evaluation research

The long-term effects of phonemic awareness training in kindergarten were evaluated by studying various aspects of reading, spelling, and oral phonological skills in school. In the kindergarten-part of the study 95 children divided into three experimental and two control groups took part. One year later 83 of them were identified and tested in school. The children who participated in the phonemic training program seemed to have benefited from it to some extent. At least they improved their scores on phonemic synthesis tests in school. Some children in the middle and high range of pretest performance seem to have avoided a risk for reading failure to a greater extent than the corresponding children in the control groups. It is suggested that phonemic training contributes to the development of accurate concepts of reading in the preschool child and makes the child less confused when confronted with formal reading instruction in school. Great variances, ceiling effects, and group heterogeneity created many difficulties in evaluating the training effects. The various methodological problems implied in evaluation research with nonequivalent control group design were analysed and illustrated with data from the present research.     

Can phonemic awareness be trained in kindergarten?

The effect of a training program designed to develop phonemic awareness skills in kindergarten was assessed in a study involving three experimental groups and two control groups. The degree of structure imposed upon the program was varied in the experimental groups. One control group was trained in non-verbal auditory discrimination, and the second control group followed the ordinary preschool program during the 6–8 week observational period. A clear improvement in the ability to segment and blend three-phoneme words was observed in the highly structured training cohdition, especially among the children with poor pre-test performance, while no clear changes from pre- to post-test were found in the other groups. It was concluded that phonemic awareness can be developed in prereaders outside the context of formal reading instruction.     

Visual constraints in reading: evidence from non-ocular behaviour

On-line evidence of visual constraints in reading is reported for measures other than eye behaviour. Text was read from a CRT using a moving window between 6 and 19 characters wide, with letters outside the window replaced by blanks, dashes, or visually similar letters. Reading speed was self-adjusted; subjects performed a subsidiary task while reading aloud. Window width and the visual context beyond the window affected dual task performance, and together with fount size, also reading accuracy. The form of text background further affected two measures of eye-voice span. These findings complement ones for ocular behaviour obtained using a CRT window coordinated with a reader's eye fixations.     

Involvement in potential future events estimated by males and females

Abstract.— Males and females from a Swedish local organization for international peace and understanding estimated their intensity of involvement in two potential future events assumed to occur in different years between 1974 and 2048. They also estimated the importance, probability, influenceability, and their knowledge of 16 future events, and the number of years before the events would occur. The results showed that males were less involved than females in an event which would increase the life span in developing countries, if this event were to occur during the next 20 years, while males and females were about equally involved in an economic depression. Compared with males, females considered that most future events were more important and they gave higher estimates for the probability of undesirable events and lower for desirable events.     

Cardiovascular and neuroendocrine activity in preschool children: Comparison between day-care and home levels

Thirty boys and 30 girls at nine day-care centers were examined at the mean age of 3.5 and 5.5 with regard to systolic and diastolic blood pressure, heart rate and neuroendocrine activity (urinary catecholamines and cortisol) during a day at their day-care center and in their home, respectively. Compared to home levels, day-care was associated with increased heart rate, epinephrine and norepinephrine excretion and decreased cortisol levels. Systolic blood pressure decreased at the day-care centers at the age of 3.5 and increased at the age of 5.5. No significant sex differences were found. The possible role of mental and physical arousal and the dissociation between the sympathetic-adrenal medullary and the pituitary-adrenal cortical responses are discussed.
